plate 4 provided at its ends with flanges b secured to the inner facesof said side plates 1 by means of screws or other fastening de vices.

The frame of the machin as constructed is supported upon the wheels 7and. S rotatably mounted on studsi) and a shaft; 10 respectively,thelatter being journaled in suitable hearings in said side plates 1Mountits ohicct to provide a simple and eilicicnt l machine of thischaracter.

'lhc invention consists In the novel features of (I )I1' lIllCllOll andco1nlnnat1on O parts herciua t'ter fully described and claimed.

In the accompanying drawings illustratiug my invention: Figure 1 is afront elevation of a machine constructed in accordance with myinvention. Figs. -2 and l are views in elevation of respectivelyopposite ends of the machine. Fig. l-- is a central verticallongitudinal section of the same. Fig. is a detail inverted plan riewshowing the di ks or saws employed and the gear train for actuating thesame.

In unloading coal from cars it is necessary to provide means for peneirating the mass of coal as nearlv as possible adjacent the floor of thecar. Where. large lumps and small pieces are intermingled as for example in mine run coal, or where block coal or in fact any of the largersizes are to be unloaded, penetration is very dillicult as will beobvious, and consequently it is necessary to exert considerable power ineffecting the same.

My invention has for its principal object to provide. a machine forunloading coal from cars which is equipped with power actuated means forpenetrating thc mass of coal adjacentthe floor in a positive andreliable manner and which is further equipped with eflicicnt means forremoving the body of the coal after such penetration has been efiected.

My said machine comprises a frame consisting of suitable side plates 1secured together at a plurality of points and mamtained parallel bymeans of cross rods 2 secured in said side plates at their ends by meansof nuts 3 in any usual. and wellknown manner. The machine is furtherprovided at the bottom thereof with a cross bevel gear 32.

ed upon one of said side plates is a bracket 11 upon which a motor 12 issupported, said motor being preferably electric. On the motor shaf'ahere is mounted a spur pinion 13 which meshes with a spur gear 14rigidly moun -2c upon shaft laq'oumaled in suitable bearings ni'the saidside plates 1 of the machine. Said shaft 15 carries a spur pinion 16rigid therewith and meshing with a Spur gear 17 rotatably mounted upon astud 18 on one, of said side platesll Rigid with said spur gear 17 is aspur pinion 19 which meshes with a spur. gear 20 011 a counter-shaft- 21suitably jourualed in bearings in said side plates 1. On saidcountershaft 2] and upon countersh'afts 22, 23 and 2% respectisely, aremounted pairs of sprocket wheels 2G, 27 and 2S respectively, over whiclrsprockct chains 29 are trained; the latter being equi pedi at regularintervals with buckets 30 or the reception and elevation of coal. Thesaid sprockets 9.6 are idle as are also the sprockets 28 While thesprockets 27 serve to transmit movement.- to the coun-Jershaft 23. Thelatter is provided at one end with a bevel gear 32 rigidtherewith andmeshing with a bevel pinion 31 on a vertical shaft 3% suitably supportedin a bearing formed in a bracket. 6 ha .ing flanges 31 secured to theouter face of one of s id side plates 1 and in a bearing .35 carried bysaid side plate, the latter being slotted at its lower end for thepurpose of pcrmicing the said spur pinion 33 to pro ect, into engagingrelation with said On the. lower end of said shaft 34 immediately abovesaid cross plate 4 there is rigidly mounted a spur gear 36 whichlikewise projects through said slot in said side plate and which mesheswith an idle gear 37 rotatably mounted on a stud carried by said crossplate 24 and which in turn meshes with a spur gear 38 rigid with thedisk 39 which is preferably equipped with teeth similar to a saw on itsperiphery;

" mounted on a spectively opposite directions.

- the stud 49 and rigid with which is pinion 50.

lever 66 the said disk 39 and spur gear 38 being stud 40 secured to saidcross plate 4. A-similar disk 41 rigid with a s ur gear 42 is driven bymeans of the pair of idle spur pinions 43 from said gear 38, the saiddisks 39 and 41 being thus driven in re- The said disks 39 and 41 aredisposed very near the lowest point in the machine, said disks beingadapted tcforce their way into the mass of coal to be loaded adjacentthe bottom of said mass at the same time that'the machine moves forward.Motion is transmitted to the frame of the machine from said motor .12 inthe following manner, to-wit: The

shaft 21 is equipped at its other end with a spur pinion 44 which mrsheswith a spur gear 45 on a stud 46 on the said plate 1 farthest removedfrom the motor 12. Rigid with said gear 45 is a spur pinipn it? whichmeshes with a spur gear 48 mounted upon a--spur The latter meshes withaspur gear 51 mounted on a stud 52 on said side plate said gear 51 beingmaintained constantl slowly in rotation. On said lastnamed; side plate 1is a stud 53 on which there is rotatably mounted a sprocket wheel 54:and a. spur gear 5-5 rigid with said sprocket. -b'aid spur gear 55meshes with two spurgear's 56 and 57 respectively, both of which arerotatably mounted on studs 58 and 59 respectively, mounted on a rockingplate fiOpivotalIy mounted upon the said stud 53. Said plate 60 isprovided with an arm or extension 61 provided witha slot- 62 in whichthe crank pin 63 on a crank arm 64 engages; the said arm 64' being rigidly mounted upon one end of the shaft (35 journaled in suitablehearings in the side plates of the machine and upon the other end ofwhich there is rigidly mounted a equipped with. an auxiliary lever 67normally maintained at one limit of its movement by means or" a spring68 engaging a longitudinal movable plunger 69 pivotally engaged withsaid lever 67 and fit'ltS lower end carryinga dog 70 adapted to beengaged in notches 71 in aplate 72 mounted upon said bracket 11. Saidlever 66 when in the position shown in Fig. 3-'ma.intains said plate 6in the position shown in Fig. 2-. By moving said lever 66 so I that thedog 7 0 engages in one of the notches gear 51 or to throw nearestadjacent the ends of said plates 72 it will serve to swing the saidplate 60 so as to throw the-gear 57 into mesh with the the gear 56 intomesh with the gear 48. On the shaft 10 there is rigidly mounted asprocket 73 over which and said sprocket 54 the sprocket chain 74 istrained so that when the gear 57 meshes withthe gear 51 the frame of themachine will be moved slowly forward toward the.

mass of coal to be penetrated and at the same time the buckets 30 willscoop up such idle rolls 7 8 arejournaled; said rolls being adapted toengage the side walls of the car and thus prevent lateral movement ofthe machine or deflection thereof from a true straight line of travel. 4

It will be obvious that the side, plates 1 will be maintained spacedsome distance from the sidewalls of the car andin order that the coalnearest adjacent said side walls shall be removed together with the bodyof coal 1 provide upon the forward edges of said side plates 1 hingedplates 7 9 which are adapted at theirforward ends to contact with theside walls of the car and throw the coal nearest adjacent said sidewalls inwardly inposition to be engaged by said scoops or buckets 30 andthus remove I claim as my'invention:
